I don't know if "out of nowhere" is really accurate since the game's been widely known since 2022, though it's nonetheless a project I'm just now learning about. With a name like Blight: Survival and referencing Resident Evil in this latest trailer's title, I was expecting there to be survival horror mechanics, but it seems to be a standard action-adventure or action-RPG game with broad horror elements. Mushrooms seem to be a contributing factor to the game's events, though one would think with a setting like this that the bubonic plague would have been re-envisioned as the cause to the zombie apocalypse.
This seems okay, but I'd like to see a closer look at the game's mechanics before making any further judgment.
